From the page's results, it seems that these steps should be able to be done in a couple of minutes on an Intel X25-M 80GB SSD. Correction: On my Intel X25-M, I was done in just over a minute: step 2 is instant.

Notes on unfreezing via suspend:
Suspending my computer to unfreeze the disk worked for me. I:

installed Ubuntu

booted it

added graphics drivers

Rebooted - but it froze on shutdown

Reset power, and found an unbootable system.

Re-launching the install showed that there were no partitions on my drive. It seems that bypassing the BIOS security left my partitions in memory of some kind.
